Episodic accretion in focus: revealing the environment of FU Orionis-type stars
O. Fehér, Á. Kóspál, P. Ábrahám +3
The earliest phases of star formation are characterised by intense mass accretion from the circumstellar disk to the central star. One group of young stellar objects, the FU Orioni…
Organic complexity in protostellar disk candidates
Jennifer B. Bergner, Rafael Martin-Domenech, Karin I. Oberg +3
We present ALMA observations of organic molecules towards five low-mass Class 0/I protostellar disk candidates in the Serpens cluster. Three sources (Ser-emb 1, Ser-emb 8, and Ser-…
Chemistry of a newly detected circumbinary disk in Ophiuchus
E. Artur de la Villarmois, L. E. Kristensen, J. K. Jørgensen +6
(Abridged) Astronomers recently started discovering exoplanets around binary systems. Therefore, understanding the formation and evolution of circumbinary disks is crucial for a co…
The ALMA-PILS survey: 3D modeling of the envelope, disks and dust filament of IRAS 16293-2422
S. K. Jacobsen, J. K. Jørgensen, M. H. D. van der Wiel +8
Context. The Class 0 protostellar binary IRAS 16293-2422 is an interesting target for (sub)millimeter observations due to, both, the rich chemistry toward the two main components o…
Interferometric view of the circumstellar envelopes of northern FU Orionis-type stars
O. Fehér, Á. Kóspál, P. Ábrahám +2
FU Orionis-type objects are young, low-mass stars with large outbursts in visible light that last for several years or decades. They are thought to represent an evolutionary phase…
Mass transport from the envelope to the disk of V346 Nor: a case study for the luminosity problem in an FUor-type young eruptive star
Á. Kóspál, P. Ábrahám, T. Csengeri +7
A long-standing open issue of the paradigm of low-mass star formation is the luminosity problem: most protostars are less luminous than theoretically predicted. One possible soluti…
